PCIE_WAKE*
I
-up to
VDD_3V3_SYS on
module
PCIe Wake: Connect to WAKE pins on device or connector. If the
module is configured as an Endpoint, include a isolator between
the wake pin on the module and the device/connector powered by
the 3.3V rail at the connector or device. The isolator should have
the output toward the connector or device. This isolates the on-
module pull-up resistors as well as ensures this signal will not be
pulled or driven high before the Root Port is powered on.
